Velocity

Meta Description: The velocity of an object is the rate of modification or change of its position with regard to a frame of reference, and with reference to time. Speed is the specification of an object. i.e. Speed and direction of motion (e.g. sixty km/h to the north).

Introduction

Velocity is a vector amount that refers to ” the rate of change of displacement over a particular interval of time

Since velocity is outlined as the rate at which the position changes, this motion ends up in zero velocity when displacement is zero. If a person in motion desires to maximise their velocity, then that person should build each effort to maximise the quantity that they’re displaced from their original position. Each step must get in moving that person beyond wherever he or she started.

Types of Velocity

1.Uniform Velocity

If an associated object undergoes equal displacements in equal intervals of time, then it’s said to be moving with a consistent velocity of uniform Velocity.

2. Non-Uniform Velocity

If an associate object undergoes unequal displacements in equal intervals of time, then it’s said to be moving with a non-uniform velocity.

Constant Velocity VS Acceleration

If any object has constant velocity, the object is moving with a constant speed in a constant direction. Constant direction constrains the thing to motion in a straight path thus, a constant velocity means that motion in a line at a constant speed.

For example, an automobile moving at a constant twenty kilometres per hour in a circular path features a constant speed, however doesn’t have a constant velocity as a result of its direction changes. Hence, the car is taken into account to be undergoing an acceleration.

Average Velocity

Velocity is defined as  the change of total displacement of an object per total time.

Let us consider that the displacement of an object is ∆x and time taken is  Δt, then the  average velocity is

Average Velocity= Total Displacement Covered / Total time

v=x/t

Instantaneous Velocity

Let us consider V as rate and X as displacement (change in position), then the instantaneous velocity of an object with respect to time t is given by:

Hence, it is given by:

v=t0x/t=dx/dt

Relationship to Acceleration

As we know that Acceleration is change in velocity, hence we determine the acceleration with velocity by that point that is acceleration is the change of velocity with respect to time.

a=dv/dt                                      From, there we can say that

Relative Velocity

Relative Velocity is the velocity of an object with respect to the velocity of another object.

Angular Velocity

In physics, angular velocity or rotation velocity, also known as an angular frequency vector, is an angular frequency measurement, which means how fast an object rotates or rotates in relation to another point, i.e. how the angular shape or shape of an object changes over time.

There are two types of angular velocity. Orbital angular velocity refers to how fast a point object turns to a fixed root, i.e. the degree of time change of angular position relative to the origin. Angular spin speed refers to how fast a solid body rotates in relation to its rotation position and is independent of the origin choice, in contrast to angular speed.

The SI unit of angular velocity is radians per second, and radian is an infinite value, so SI units at angular velocity may be listed as s-1. Angular velocity is usually represented by the omega symbol (ω, sometimes Ω). Basically, the positive angular velocity indicates the opposite rotation of the clock, while the negative rotation corresponds to the clock.

Angular speed plays a prominent role in the rotation of an object. We already know that in an object with a circular motion all the particles move in a circle. The linear velocity of all participating particles is directly related to the angular speed of the whole object.

The two end up being vector products related to each other. Basically, angular velocity is a vector value and rotation speed of an object. The angular removal of a certain period of time gives the angular velocity of the object.

Conclusion

Velocity measures when motion begins in one place and heading toward another place. The sensible applications of velocity are endless, however one amongst the foremost common reasons to live velocity is to see however quickly you (or something in motion) can reach a destination from a given location. Basically, Speed is a scalar quantity and does not keep track of direction in consideration and whereas velocity is a vector quantity and is direction aware that means it take direction into consideration.
